In the accompanying drawings I have shown `ene form of apparatusembodying my invention. This form is shown by Way of illustration merelyand is intendedA to illustrate the idea of my invention,withoutnecessarily limiting myinvention to the construction shown.

In the drawings, Figure lis a sectional elevation of the apparatus, thefront of the case being removed. Fig. 2 is a plan view thereof. Fig. 3is a diagram of the circuits, and Fig. 4 is a section through the lampand instrument-carrying holder. Fig. 5 is a detail side View of thedevice for holding a spatula or other instrument. This figure also showsthe line 4 4 on which the Asection Fig.v 4 is In the drawings, a is asuitable casing in which are journaled suitable spring-barrels b c.Insulated conducting-wires ef g 7e are provided for supplying current tosuitable electric lamps 1l j. One of the wires, let us say e,isconnected to a conducting-baud Zof the spring-barrel b, andthe other ofthe said wires fis connected to a conducting-band m of the saidspring-barrel. In like manner the wire g is connected to theconducting-band n of the other spring-barrel and the wire k connected tothe other band o of the spring-barrel c. 'Ihe contact-brush m',carriedby the casing, bears upon the band m; a contactbrush Z', carried by thecasing, bears upon the band l; acontaet-brush fn', carried by thecasing, bearsupou the band n, and a contactbrush o', carried by thecasing, bears upon the band o. The contact-brush n' is connected to acontact-plate p by wire q, (seel Fig. 3,) and the contact-plate Z isconnected to the contact-plate r by wire S. The battery is herein shownas ordinary dry cells t, connectedin series, and one terminal thereofconnected to the wire q by a suitable plate or contact 1J and the otherterminal connected to the plate fr. A suitable pivoted switch u isprovided for closing circuit between the contacts r and o', and anothersuitable pivoted switch lu is provided for closing circuit between thecontactp and the brush m. The lamp carrier or socket i', which carriesthe lamp e', is provided with a suitable hook or fastening device 2 forhanging the lamp upon the clothing of the physician. The lamp j-iscarried in a suitable socket j' in the elongated holder w. Thisholder'w, as shown in Fig. 4, consists'of an external shell .72, formingone terminal of the device,.and an interior rod j3,

which is adapted to contact with the central contact of the lamp. Theelongated holder w is seated on a plug or, which is likewise formed witha central contact and a surrounding contact. The elongated holder w isprovided with -a tubular socketgj4 for receiving the Shanks of suitablesurgiml instruments and likewise with a pair of oppositely-placed jawsor flanges '7'5 for receiving the curved shank of a spatula or otherinstrument 3". These jaws extend longitudinally of the body w. l

As illustrating the convenience of my device, let it be supposedthatuthe surgeon dcsires to examine a patients throat. IIe hangs thelamp e' upon his coat or forehead, using a band around his forehead to.receive the hook i2 and by employing the combined lampholder andspatula can illuminate the laryngeal cavity of the throat directly bymeans of the lamp carried in the same instrument as the spatula and alsoby means of the lamp fi. It will be observed that the case (L is dividedinto two chambers by the partition a. The lower chamber a2 contains thebatteries, and the upper chamber a3 is adapted to contain the otherparts of the device. pose the wires which wind on the spring-barrelafter the manner of the Hartshorn roller Vvpass freely through theapertures ai* in the partition a', so that by uuserewiug the elongatedholder Iw from its socket m, unserewing 'the lamp j and placing itbetween the resilient jaws y, and removing the spatula j from theelongated holder fw all the parts which are not contained within thechamber a2 lamp, thesaid conducting-wires being elec' trically connectedto terminals carried upon an automatic spring-barrel carried by thecasing and circuit connections between the battery and spring-barrel,substantially as described and for the purposes set forth.

2. In an electrical apparatus for surgeons may be packed into thechamber a3 and the swing-- mg c over a5 may be swung down and securely'use, the combination of a casing divided into two chambers, a batterycontained in the lower chamber, a spring-barrel, in electricalconnection with said battery, electrical conductorsalso connected tosaid spring-barrel and anelectric light connected to the said electricalconductors and adapted to be housed in the upper chamber of thestructure.

3. In an electrical apparatus for surgeons use, the combination of acasing, an electric battery carried thereby, a spring-barrel providedWith insulated cond ucting-wires-in electrical connection with anelectric lamp, contact-brushes adapted to maintain a rubbing contactwith the spring-barrel and electrical connections between the batteryand said brushes.
